How to read this result

Three useful checks, kept deliberately short.

What this result includes

The volume is 72 mΒ³ and the surface area is 108 mΒ².

A practical example

A rectangular prism measuring 6 m Γ— 4 m Γ— 3 m: Multiply all three dimensions for volume Β· Calculate the three face-pair areas Β· Double their sum for total surface area.

Common input mistake

Real containers may have wall thickness, openings or irregular profiles that are not included.

Formula and assumptions

Volume and Surface Area Use the Standard Formula for the Selected Solid Shape

Cylinder and cone inputs use radius and perpendicular height; a sphere uses radius only.

Keep in mind: Confirm which dimension represents radius, height, width or depth before calculating.
